Detailed explanation-1: -Explanation: This is a synthesis reaction, also called a combination reaction, in which the metal beryllium reacts with oxygen gas to produce the solid beryllium oxide.
Detailed explanation-2: -This is a combination reaction because the Be and O2 come together to form beryllium oxide. Put a 2 in front of the BeO.
Detailed explanation-3: -Beryllium is passivated by oxygen, forming a BeO surface. Normally beryllium cannot be oxidized, even when heating to 600 °C, but powdered beryllium can be brought to burn in air, forming beryllium oxide, BeO and beryllium nitride, Be3N2.
Detailed explanation-4: -Beryllium oxide (BeO), also known as beryllia, is an inorganic compound with the formula BeO.
Detailed explanation-5: -Beryllium oxide (BeO) is a white crystalline oxide. It occurs in nature as the mineral “Bromellite”. Historically, beryllium oxide was called glucina or glucinium oxide.
